Key findings

• In recognition of the need for ongoing monitoring of new or less common drug types, the Australian Institute of Criminology (AIC), as part of the Drug Use Monitoring in Australia (DUMA) program, interviewed 824 police detainees about their knowledge of and experience with mephedrone, GHB, Ketamine and Rohypnol.
• Mephedrone was the least known of the four drugs, with only 221 detainees (27%) reporting knowledge of the drug. Only six detainees (<1%) had used the drug in the previous 12 months, while 30 detainees (4%) knew of someone dealing mephedrone at the time they were interviewed. Detainees in East Perth were the most likely to have reported knowledge of mephedrone.
• GHB was known to more than half of all detainees interviewed (53%) and had been used in the 12 months prior to interview by 23 detainees (3%). More detainees had been offered GHB (8%),
  or knew of a dealer selling GHB (6%), than any of the other four drug types.
• Ketamine was known to 43 percent of detainees and had been used by three percent. The prevalence of Ketamine use was equal with GHB, however, knowledge of a current Ketamine dealer was lower (4%).
• Rohypnol was the most widely known of the four drug types (59%), however, use of the drug in the 12 months prior to interview was lower than for GHB or Ketamine (1%).
